Marine Weather and Tides
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Dry weather is expected much of this week, with our warmest
weather of the spring season thus far. By Thursday and Friday,
some of our lowland areas will have a shot of reaching 80 degrees
or more. Toward Saturday changes are possible, with some threat of
showers and maybe thunderstorms returning.
Today through Monday night: the cirrus deck has moved out of the
region leaving us with mostly clear skies. However, satellite
shows another area of mid and high clouds currently moving onshore
over western oregon and washington headed east. The NAM is
representing this feature well in the 500-300 mb rh field,
associated with a weak wave in the upper level flow. It looks to
bring a deck of clouds to the region beginning this morning and
exiting by this evening, though the lee of the cascades will
likely clear out earlier in the afternoon. Any precip chances from
this wave stay well south of the area in central idaho. Starting
this evening a strong high pressure ridge begins building in which
will give us sunny skies, temperatures in the mid 60s by Monday,
and our warmest week of 2018 so far. Bw
Tuesday through Saturday: dry and warm weather expected most
of this period, but changes are possible by the end of the week.
Tuesday to Thursday the region will be dominated by high pressure,
briefly damped by a canadian trough Tuesday night and Wednesday.
At the same time a cut-off low is projected to set-up off the
pacific coast. Aside from some flat afternoon cumulus and
transient high clouds, the region will be mostly clear and dry.
Toward Friday and Saturday the cut-off low attempts to move
inland. Unsurprisingly models disagree over its precise evolution.
Cut-off lows have no solid steering mechanism and tend to move of
their own volition. With the ridge axis over the area early this
period shifting toward the northern rockies the southerly flow
will help promote warming temperatures. Regional 850mb
temperatures in the lower teens warm to the middle to upper teens
by Friday, before dipping some Saturday. This will lead to the
warmer conditions, with many areas warming from the 70s Tuesday to
the upper 70s and 80s by Friday, before some cooling Saturday.|
This warmth will come with some unstable conditions. Precisely how
much instability there will be and where it will set-up is
uncertain but any disturbances rounding the cut-off low and
ejecting through our region will bring a threat of showers and
thunderstorms. Friday the main risk will be south of the area but
i cannot entirely rule out some around the blue mountains. Some
guidance brings the threat north into the upper columbia basin,
palouse and even toward the spokane area Friday night. However
confidence is too low to include in the forecast at this time.
Saturday (into next Sunday) broader chances envelop the region,
but these still look to be isolated to scattered in nature and the
better risk will be around the mountains and southeast cwa.
The other issue will be rises on area waterways due to snow-melt,
more noticeably mid-week on. At this time none of the mainstem
river area projected to flood in the next week, but some may push
toward bankfull and these will be monitored. However small
streams creeks may spill over, even without precipitation. J. Cote'
18z tafs: mid and high clouds will continue through 02z to 03z
with winds below 10 kts andVFR conditions. Mwh eat will
experience brief gusty winds to 15 kts through the afternoon.
High pressure builds in overnight bringing clear skies. Bw

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
